Breast Ultrasound
Breast ultrasound uses the same high frequency sound technology used to visualise the foetus in a pregnant woman, but is applied to the breast tissue using equipment specific to the breast (high frequency ultrasound probes).
Method
The ultrasound examination does not use x-rays to produce the images.
The ultrasound technique obtains images that are complementary to the mammogram.
Patients frequently have both a mammogram and a breast ultrasound.
Use
Ultrasound can be used to assess the following:
Very dense breast tissue
Patients who have a clinical abnormality (a symptom), but where no abnormality was identified using mammography.
Younger women in whom the risk of breast cancer is less
Pregnant women thus avoiding the use of x-rays
Assessing the nature of lesions seen on the mammogram.
Time
The ultrasound procedure takes approximately
30 minutes
